【教學】[原創] TECOM AR4031B、Wagaly Talk 連接線之組成

[hungwen]

小弟有點糊塗, 按照前面的說法, 紅、橙線分別為 RX、TX, 黑線為 GND, 這是對應到PC 9-pin D-Dub 而言, 則面對AR4031B 左側之 4Pin 接頭, 由左至右分別為TX,RX,NC,GND, 您此處是否誤將紅、橙線打成紅、棕線?

文中提到的 RX、TX 均是以 AR4031B、Wagaly Talk 為主, Wagaly Talk 為紅、橙、棕、黑, AR4031B 則為 棕、橙、紅、黑.

有圖有真相... 以下是 AR4031B 之接法:

[FYI]

文中提到的 RX、TX 均是以 AR4031B、Wagaly Talk 為主, Wagaly Talk 為紅、橙、棕、黑, AR4031B 則為 棕、橙、紅、黑.

小弟之前無法確定方向性, 一直以為由左至右(022hf.jpg), 原來您是由右至左, 還是看圖說故事比較容易瞭解, 那麼面對AR4031B 左側之 4Pin 接頭, 由左至右分別為GND、RX、TX、NC, 如果連接至9-pin D-Sub, 則黑、紅、橙線分別連接Pin5(SG)、Pin3(TX)、Pin2(RX)


補充:
小弟終於也把AR4031B 拆了, 果然板子上有不少預留接點, GND, +12V 等, 小弟比較好奇的是那神秘的第四pin 會是什麼訊號? 扣除成對的訊號之後, 就只剩下CD/RI

[hungwen]

小弟比較好奇的是那神秘的第四pin 會是什麼訊號?

應該是 VCC +3.3V.

剛剛拆了兩台 AR4031B 的外殼, 再用三用電表進行量測之結果, 分別為 +3.28V 與 +3.29V, 數值比較接近 +3.3V.

[hungwen]

這是 Wagaly Talk 的接法...

[hungwen]

剛剛把連接線接到 Alcatel T07L011 上(紅 -> 2, 橙 -> 3, 黑 -> 5; 速率設為 57600,8,N,1), 可以正常連線...










這是用 2mm 立體聲母座 + DIN-PS2 鍵盤轉接線改裝而成的 T07L011 連接線:

[hungwen]

以 Alcatel Speed Touch 340 來進行測試(紅 -> 2, 橙 -> 3, 黑 -> 5; 速率設為 9600,8,N,1), 也可以正常連線...

加油,快破解AP吧!

Alcatel T07AW 之 Wireless 功能開啟程序 (hungwen@PCZone):
需以 Console 連接線 (製作方式與 Alcatel T07L011 相同, 但是 RX、TX 與 Alcatel T07L011 相反, 建議用 DIN-PS2 鍵盤轉換線來改裝) 與 Alcatel T07AW 連接, 使用 Hyper Terminal 來登入 Alcatel T07AW (115200,N,8,1) 進行下列操作.

在 Wireless 功能開啟後, 再以 Web 連線方式登入 Alcatel T07AW, 就可以看見多出一個 "Wireless" 設定選項...


註1:進入 CFE (Boot Loader) 之後, 請小心使用這兩個指令:e 與 i, 這兩個指令功能並不等同於 "Restore to Default", 以免造成無法挽救之結果.

註2:由於 Alcatel T07AW 採用 Broadcom BCM6348 晶片, 因此也適用這篇文章之操作程序.

[hungwen]

以下操作程序僅適用於 TECOM AR4031C (使用 Broadcom BCM6338 晶片), 不適用於 TECOM AR4031B (使用 Broadcom BCM6335 晶片), 與 "Hacking Beetel 220x ADSL router (Broadcom BCM6338)" 這篇文章有些不同, TECOM AR4031C 需使用 Console 連接線進行操作, 在輸入 Ctrl-C & Ctrl-D 之後可以中斷 Shell script, 但是若是使用 Telnet 連接方式, 在輸入 Ctrl-C & Ctrl-D 之後, Shell script 中斷後 Telnet session 會被退出結束.
